Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The CMFEditions component 2.x in Plone 4.0.x through 4.0.9, 4.1, and 4.2 through 4.2a2 does not prevent the KwAsAttributes classes from being publishable, which allows remote attackers to access sub-objects via unspecified vectors, a different vulnerability than CVE-2011-3587.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-264

A legacy NVD category covering weaknesses where permissions or privileges are assigned, checked, or dropped incorrectly, so an action ends up running with more access than it should. It is an umbrella label from older records, not a single flaw. The remedy depends on the specific case, but the throughline is least privilege with explicit, checked transitions wherever privilege changes.

Recommended fix High confidence

Plone 4.0.10 or later (or 4.1.4+, or 4.2+)

  1. 1. Back up your current Plone database and site data before any upgrade.
  2. 2. Stop the Plone instance.
  3. 3. Upgrade Plone from version 4.0.x to version 4.0.10 or later (or to 4.1.4+, or 4.2+).
  4. 4. If using buildout, update your buildout configuration to specify the target Plone version.
  5. 5. Run the Plone upgrade procedure to migrate the database.
  6. 6. Restart the Plone instance.
  7. 7. Verify the CMFEditions component is functioning correctly and the vulnerability is remediated.
Caveat Upgrading across minor versions may require testing of customizations and third-party add-ons for compatibility
